Uniformity of adherence definitions according to whether the biometric monitoring technology (BioMeT) was a passive, session-based, or task-based tool. Passive BioMeTs are those designed for continuous use. Active BioMeTs are those that require user engagement at defined time points, further categorized as session-based (for which duration of use is meaningful) versus task-based (for which the duration of use is not meaningful). The colored bands represent unique definitions of adherence within each bar. The colors are comparable across the bars within each category of adherence definition (duration of use, number of measurements, and categorical variables).
